Whether you want to save your phone's memory (and battery) or need your on-the-go sound to be as good as it can possibly be, look no further than our pick of the best MP3 players on the planet.
Despite the demise of the iPod (Apple waved goodbye to the last remaining model in May 2022), the traditional portable music player has by no means been consigned to the scrapheap. The iPod, and latterly the smartphone, may have come to dominate the mainstream market, but there's so much more to discover than those products sporting a piece of half-eaten fruit stamped on the back.
While smartphones now satisfy most users' demand for on-the-go musical delivery, there are still dozens of dedicated players that can go even further in delivering high-quality audio from your pocket. Thanks to hands-on testing for each and every one of the products below from our expert listening team, you can rest assured you'll find the ideal music player for the right price.
We've tested many players from Cowon, FiiO, Sony and more over the years, although the higher-end Astell & Kerns are having a stellar year (or two) and dominating our best lists at every budget – for the moment. We're reviewing new Sony Walkman and FiiO models, so we'll be sure to add those once they've been officially reviewed. Below, we've rounded up the current best MP3 players across a range of prices to ensure you know exactly what to look for and where to find it.
How to choose the best portable MP3 player for you
Why you can trust What Hi-Fi? Our expert team reviews products in dedicated test rooms, to help you make the best choice for your budget. Find out more about how we test.
Whatever your budget, you will be surprised at what you can get for your money these days. Every player here supports MP3 and AAC files of course, but we can all do better than that in 2023. All of the models below also support hi-res files (such as DSD, FLAC and PCM files), with some also adding native MQA playback to that compatibility list, so you can listen to hi-res Tidal Masters through compatible players and playback downloaded MQA music in the best sound quality possible.
Have an extensive digital music collection? Many of these MP3 players have microSD memory slots, so your assembled throng of tracks and artists need never stop growing. Expandable memory also means you can keep all of your music at the highest quality possible, without worrying about those large file sizes taking up all of your player's storage space.
There are even MP3 players here that can double up as a DAC to enhance the sound between your smartphone/laptop and headphones/speakers. Some have built-in access to streaming services, too, while others have even more functionality that mirrors a phone's.
But all of the products in this list have one thing in common: excellent sound quality. And if you're here, that is probably the aspect that's most important to you in a portable MP3 player.

The Astell & Kern A&norma SR25 MKII is the latest in what has been a long line of excellent, What Hi-Fi? Award-winning, ‘entry-level’ portable music players. And each new generation invariably proves more talented than the last.
The SR25 MKII doesn’t let us down, propelling its lineage forward from the 2018-introduced A&norma SR15 (also in this list) to set a new performance benchmark. Last year, it was a What Hi-Fi? 2021 Award-winner, and this year, it took the best portable music player over $1000 What Hi-Fi? 2022 Award.
Notably more expressive and eloquent than any other portable music player we have encountered at this price, and far beyond anything that smartphones are capable of, the SR25 MKII demonstrates just how good music on the move can sound, while also remaining reasonably affordable. And we stress the word 'reasonably': because while it pushes performance forward, it also pushes what is acceptable as an entry-level price.
Still, if your budget can stretch to it, this is a truly stunning player with superb build quality to match.

How about a customisable PMP with interchangeable DAC modules? That's the idea here – and we liked it so much, we gave it What Hi-Fi? 2021 and 2022 Awards. The new SE180 is the third model in Astell & Kern’s near-flagship A&futura range, following the inaugural SE100 and SE200, both of which gained Awards from this very publication in 2019 and 2020 respectively (and are listed below).
To personally tailor your sound, the SE180 goes one step further than the slightly older SE200 (which has two user-selectable DAC configurations built into the player) in that it features an interchangeable DAC module design. The concept: Astell & Kern releases a series of DAC modules, all with different sonic characters, so that owners can purchase them and swap them in over the standard supplied module, if they so wish.
Of course, these can be considered optional extras; experimental paths that can be taken or completely ignored. After all, the SE180 is an all-in-one player in itself, with the default module containing the ESS ES9038PRO DAC. It supports 32-bit/384kHz PCM, native DSD256 and MQA audio and has 2.5mm, 3.5mm and 4.4mm outputs to cater for a wide range of headphones.
With built-in wi-fi as well as direct access to streaming service apps in its menu, the SE180 doesn’t make hard work of your music however you would like to play it. Whether you consider the modular design valuable or not, even straight from the box, the SE180 is one of the best performance-per-pound offerings in the company’s line-up.

Arguably the ultimate high-resolution portable music player in this price bracket, the Kann's solid build combines with impressive battery life and a long list of features.
There are both unbalanced (3.5mm) and balanced (2.5mm) outputs, aptX Bluetooth for wireless streaming at better-than-CD quality, and native support for 32bit/384kHz and DSD256 files.
As for the performance, there’s lashings of depth, detail, and dynamism that will make you reluctant to take off your headphones. It keep instruments precisely organised in a spacious presentation, while bass drums are conveyed with tenacity and force – the Kann digs down into the lower frequencies and presents them with a good deal of thump so you get a clear indication of the drummer’s force.
Even when fed lower-resolution tracks via streaming services, the Kann maintains its character. While there is an expected drop in detail, it’s still punchy and fun. If you want to show off how impressive good hi-fi can be, it’s not compulsory to buy more hi-res files.
Admittedly the aesthetics might raise a few eyebrows – and the newer Kann Alpha is a slightly more svelte model. But make no mistake, this is a talented machine you will struggle to put down.

Not many portable music players will find common ground with the SP2000 – and that goes for price, build and performance. This is a one-of-a-kind player, which is as impractically portable as it is inaccessibly priced.
If it were a car, it would be a Bentley Arnage – a luxurious ride for special occasions, rather than something to use for the weekly shop.
As a high-end music player – both as a straight-up PMP in a desirable headphones set-up and as a streaming-capable source for your speaker-led hi-fi – the A&ultima SP2000 is the sort of musical and multi-talented device that is otherwise hard to come by.
Its neutral balance opts for refinement and sophistication over outright liveliness, but that’s no criticism. This is a subtle presentation, rather than a barnstormer, which befits its high-end price tag. Forgive its weight and average battery life, and you won’t be sorry you chose this fantastic-sounding device.

How we test portable music players
We have state-of-the-art testing facilities in London, Reading and Bath, where our team of experienced, in-house reviewers tests the majority of hi-fi and AV kit that passes through our door, including the higher-end portable music players that might well be used in a portable hi-fi or desktop scenario.
These music players are placed in our pockets during the review period too, of course, so we can gauge how portable and easy to use on the fly they really are.
Most important in our reviewing process is that each product is compared with the best in its price and class. What Hi-Fi? is all about comparative testing, so we keep our Award winners nearby to enable comparisons between new products and ones we know perform highly in the category.
We are always impartial and do our utmost to make sure we are hearing every product at its very best, so we try plenty of different types of music and give each plenty of listening time (and time to run in). We use a range of headphones at levels likely to suit a certain player, too.
It's not just about sound quality, of course. If a product has noteworthy features – such as battery life, built-in streaming services and DAC-performing abilities, in the case of portable music players – we always ensure part of our testing involves testing the claims made by its makers.
All review verdicts are agreed upon by the entire team, rather than an individual reviewer, to eliminate any personal preference and to make sure we are being as thorough as possible. There is no input from PR companies or our sales team when it comes to the verdict. At What Hi-Fi?, we are proud to deliver honest, unbiased reviews – something we have been doing consistently for more than 45 years.
